I was about to have a shower______ the telephone rang at the bedroom. A. as B. when C. at the time D

I was about to have a shower______ the telephone rang at the bedroom. A. as B. when C. at the time D. and

The correct answer is B. when. This sentence requires a conjunction that expresses a sudden interruption, where one action was in progress ("was about to have a shower") when another action occurred ("the telephone rang").

"When" is grammatically appropriate here because it introduces the unexpected event that interrupts the main action.

"As" (A) typically indicates simultaneous actions ("I sang as I cooked"), not interruption.

"At the time" (C) is a phrase, not a conjunction, and would require additional structure ("I was about to shower at the time the phone rang").

"And" (D) suggests sequential or parallel actions, not an interruption.

The completed sentence reads: "I was about to have a shower when the telephone rang in the bedroom." This construction clearly conveys that the phone call interrupted the planned shower. Why might "when" feel more natural than other options here? Because it creates a sense of immediacy between the two actions, emphasizing the unexpected timing of the phone ring.
